Nomenclature Flashcards
how is methane formed naturally?
plant decay in anaerobic conditions, eg a marsh
what does IUPAC stand for?
International Union of Pure and Applied Chemistry
what did the IUPAC do for organic compounds?
introduced rules for naming them
the IUPAC’s naming rules are known as
‘nomenclature’
we can summarise the nomenclature rules as
prefixes, suffixes and locants
OH represents a ….. group
hydroxyl
methylpropane does not require a locant because
if the methyl group was attached at the end of the chain, we would have butane
the ….. locant should always be used
lowest
when we have multiple prefixes, they must be written in
alphabetical order
suffixes are used for groups such as
alcohols, where the -ol appears at the end
draw out 3,3-dimethylbutan-1-ol
check your sketch
the longest carbon chain is not always
shown horizontally
